fsniper - detects changes in directories

Here's an interesting tool that could be used for a number of applications that need to detect when files have changed in a directory.

From the project website:

"fsniper is a tool that monitors a given set of directories for new files. Then, based on the new file's type or name, it invokes a script to be run (any executable via the shell) on that file.
Common uses include making a single drop directory for all things from a webbrowser etc, and having semi-intelligent scripts figure out what to do with those files. You write the scripts yourself. "
